My little one is 4 weeks and recently she seems to be getting frustrated mid feed. She usually stays on the first side for about 10 mins then falls asleep and comes off. I then wind her and change her nappy (HV has advised me to try and wake her up to give her longer feeds) when I try to put her on other breast she gets really frustrated kicking her arms and legs and crying. I've just managed to get her to have about 5 mins on second side but the whole feeding session has taken well over an hour. She doesn't seem to have much gas so don't think its wind or colic. Any ideas?
